SPIRAL FAN ASSEMBLY

摘要

PURPOSE: A spiral fan assembly is provided to reduce the size of a blowing fan system having the spiral fan assembly without limiting an installation space of the spiral fan assembly by generating a great amount of wind having great wind pressure. CONSTITUTION: A spiral fan assembly includes a rotating shaft(11) rotatably coupled to a driving motor, a cylindrical hub(12) fixedly coupled to the rotating shaft(11), a plurality of blades(13) formed at an outer peripheral portion of the cylindrical hub(12) in a spiral pattern, and a fan housing(14) surrounding a rotational route of the blades(13). The fan housing(14) has a hollow cylindrical structure both ends of which are opened. A plurality of pores(15,16) are formed at side portions of both ends of the fan housing(14) so as to allow air to be introduced or exhausted through the pores(15,16).
